SPECIFICATION formingpart of Letters Patent No. 271,778, dated February', 1883.

' 1 application tuen July 15,1882. (No model.)

To all4 whom it" may concern: i

Be it known that I, J. J. BOWKER, a citizen ofthe United States, and a resident of La Otto, in the count-y of Noble and State ot' Indiana, have invented a new and valuable Improvement in Chairs; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation ot' the same, reference being had to the annexed drawings, making a part ot' this specitication, and

i novel arrangement of parts, as will be hereinafter fully described and claimed.

. In the accompanying drawings, the letter A designates the seat-frame of the chair, whereof'the side bars. B, project somewhat in front, and are vertically slotted inV theirfront ends, as indicated.,

(-epresents the legs of the seat-frame, which are usually perforated upward from their lower ends to forni bearings to receive the long stems a ot' the casters b. By means of these adj ustable casters the height ofthe seat-frame can be varied to suit the requirements ot' the occupant, the casters being secured in position aiter adjustment by means of set-screws c.

"C represents the back of the chair, having the side bars, D, which are vertically slotted at their lower endsrto receive the circularlyexpanded or disk-shaped pivot-heads d of the pivot-slides E, which have reciprocating moside bars, B, of the seat-frame.

tion hack and forth in the"slide\vays`F of` the Each pivotslide'E is provided with a set-screw, c, whereby it is secured in position -at'ter adjustment in its slideway. The sidebars, D, of the back of the chair are also provided with slideways F, in

`which the pivot-slides E of the arms G are adjustable. The disk-heads d ofthe pivot-slides of the chair-back are seated in vertical slots g,

formed in the rear ends ofthe arms G, and are connected thereto by transverse pivots h. In

a similar manner the pivot-slides E of the arms G are connected in vertical slots g in the wrear ends of the fore arms, H, by pivot-pins h,

said slides being adjustable in slideways F, attached to the under sides of the arms G. Each fore arm, H, is provided with a pivot-disk, l, which is seated in the vertical slot g in the front of the snide bar of -the seat-frame, being connected therein by a transverse pivot-pin, 7L. To the rear portion of the fore arniis connected a curved brace, K, which extends downward through a slot, 7s, in the seat-bar B, and

is adjustable therein, the adjustment being se' cured by meas of a set-screw, n, which passes through a bearing in the seat-bar. `This arcbrace K is `in rear of the pivot in the front end ot the seat-bar, and by the adjustment of said brace the angle ot" inclination ot' the forearm is determined. This adjustment also governs to some extent the heightof the side arms and the inclination ofthe back of the chair, as the back is connected by means of the side arms to the fore arms in such a manner that when the braces are secured in position the back and side arms, as well as the fore arms, are alsoV fore arms and side arms are in iixed position,

by means of' the slide-pivots E 'at the lower ends of the side bars of the back. So, also,

4the height of each side arm in rear can be alterrd by meansof the adjustable pivot-slides E', connected to slideways on the back bars.

Siideways F' are provided on the upper surfaces lof the fore arms, H, and in these slideways are engaged the arms or bearings 1J of 85 the sliding'foot-rest L, which is in this manner made adjustable. Set-screws h" are provided to tix the adjustment of the foot-rest;

This reclining-chair is readily and cheaply constructed, as the pivot-slides and their slideways are of similar pattern. `It is easily adjusted to suit a large or small person, and to hold the person either in an upright sitting posture or in a reclining position at any desired angle.

The arms, legs, and back of a folding chair have been pivoted together t-o permit the chair to be folded, when desired, prior to my invention, and the foot-rest ot' an invalid-chair has been rendered adj ustable on its frame by ad- ICO of these constructions is claimed herein.

j ustable ratcheted slides engaging fixed ratchets on the side bars of said frame; but neither their adjustable slidelconnections,'of the pivotdisks of tne fore arms seated in end slots of 15 the seat-bars, and the curved adjustable braces connected to said fore arms and extending through slots of the seat-bars, substantially `as specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence ot', two witnesses.
